Abstract: The article addresses the evolution of the global energy matrix, highlighting the transition from the use of coal to oil as the main energy source, driven by the growth of the automobile, transport and civil construction sectors. The article also differentiates onshore exploration methods, classifying reservoirs as conventional and unconventional. Conventional ones have high porosity and permeability, while unconventional ones, such as shale gas, require specific techniques for extraction, such as hydraulic fracturing. The economic viability of this exploration is related to the reduction in operational costs and the technical challenges imposed by the low permeability of geological formations. Finally, the text highlights that the exploration of shale gas represents a dilemma between economic potential and environmental impacts, requiring a careful analysis to determine its viability within the Brazilian energy matrix.
